Heater construction



Patented Mar. 17, 1942 UNITED STATES PATENT oTFIcE HEATER CONSTRUCTIONGeorge Famos, Philadelphia, Ta.

Application January 25, 1939, Serial No. 252,733

1 Claim.

This invention relates to heater construction and more particularly to acrown component or section for domestic and similar heaters, the primaryobject being to provide a novel type of crown component for thesuspension therefrom of a heat retainer and diffuser unit of the typedisclosed in my prior application for patent Serial No. 249,675, i'lledJanuary '7, 1939, and which later matured as U. S. A. Patent No.2,200,985, dated May 14, 1940.

Another object is the provision of a crown component or section which isadapted preferably for new heaters, but which may be substituted forexisting heater top sections, whether round or of the sectional type.

The invention further ccmprehends certain features of construction,combinations and arrangements of parts that will hereinafter more fullyappear, and be particularly pointed out in the concluding claim.

Reference will now be had to the accompanying drawing, in which thereare exhibited practical embodiments of the invention.

In the drawing:

Fig. I is a broken vertical section of a standard type domestic roundheater embodying one form of the present improvements.

Fig. II is a broken plan section, taken approximately on the planedesignated II-II in Fig. I.

Fig. III is a fragmentary vertical section of a modified form of thisinvention.

Referring in detail to the drawing, and rstly to Figs. I and II moreparticularly, the improved heater component or section I, therein shown,embodies a hollow annular portion 2, with an intermediate andcommunicating chamberedcrown 3, having a central draft orifice 4therethrough. The section I is preferably of cast metal, and it isprovided, at predetermined points, with integrally-formed axially coredout hubs or studs 5 for passage of the screw-threaded upper portions 6of suspension members or rods 1, said rods being rigidly retained inposition by upper and lower lock washers 8 and nuts 9. Or, as shown inFig. III, the central draft orifice 4 may include upper and lowerspiders I0, II, respectively, formed integral with the component I, andeachhaving an axial opening I2 for passage of a single suspension rod 1with applied clamp nuts I3. Each of the suspension rods 'I has the loweror other end screw-threaded at Ill, and is fitted with a lock washer I5and nut I 6, for a purpose later explained.

Adapted for support by the rods 'I is the substantial heat-retainer anddiffuserunit 20, preferably of the type set forth in the hereinbeforereferred to patent, said unit having borings 2| therethrough for passageof the rods 1, and it is sustained at the required elevation, relativeto the crown section I, by the lock washers I5 and nuts I6, in anobvious manner. The unit 20 also includes surrounding baffles 22, and aspreader 23 to prevent unconsumed fuel particles entering ythe centraldraft orifice 4. I

In Fig. III, it is to be noted the upper screwthreaded portion 6 of thesuspension rod 1 is provided with an additional nut 24 functional toinitially support the spreader 23 when assembling the unit 20 below theheater section I, whereby the necessity of otherwise holding saidspreader is eliminated while adjusting the heat-retainer and diffuserunit 20 in position.

From the foregoing description, it is thought the merits and advantagesof this invention will be clearly understood, also that minor changesare comprehended as coming within the scope of the following claims.

Having thus described my invention, I claim:

A component section for domestic heaters comprising a hollow annularportion, a transverse communicating planar section intermediate theupper and lower ends thereof, a draft orifice through said section, andapertured means integral with the walls of the planar section; incombination with a heavy heat retainer-anddiifuser unit having boringstherethroughfor alignment with the heater component planar sectionapertured means, and suspension means engageable through the said unitborings and component section apertured means for 'central support ofthe former pendently by the latter.
